Project Runway Season 2 was the second season of Bravo's successful Project Runway, a reality competition for fashion designers. Season 2 began airing on December 7, 2005. Following a nationwide search earlier in the year, sixteen designers were chosen as semi-finalists and brought to New York City in June 2005. After the first challenge, called "Road To The Runway", fourteen went on to compete as finalists. The winning designer, Chloe Dao, received $100,000 in seed money to help launch her own line, a 2007 Saturn Sky roadster, a spread in ELLE magazine, and a mentorship with the Banana Republic Design Team. Winning alongside Dao was her model, Grace Kelsey, who received the ELLE Magazine spread. Michael Kors and Nina Garcia returned as judges for the second season. The fourth judging seat rotated each week, based on the challenge. Tim Gunn, fashion chair at Parsons The New School for Design, returned as a mentor for the designers.

Daniel F. had been a competitor in the first season and was eliminated in that season's first episode. Determined to show that the judges "made a mistake" in eliminating him so soon, he returned to the nationwide tryouts with samples from his own design line. The evaluation panel at the tryouts decided to give him one more chance and brought him back as a contestant for season two.

Before arriving in New York, the 16 contestants being considered for positions in this season's competing cast were given six yards of plain white muslin, $20, and one week to create an outfit that best represents who they are as a fashion designer. After arriving, the 16 contestants found that only 14 positions were available in the Parsons workroom and thus two would be eliminated at the runway judging.

Designers made an outfit using only the clothes they were wearing at the moment the challenge was announced. They had one day to complete their designs. This episode is best remembered for Andrae's tear-filled panic attack on the runway, and the judges relatively unfeeling response.

Designers created a life-sized outfit for the My SceneBarbie collection. The winning designer's outfit would be duplicated for the My SceneBarbie collection. The designers had a budget of $150 and two days to complete the design.

Designers created a lingerie line consisting of three looks. A team event with four teams, each with a lead designer and two assistants. The designers had a budget of $200 and one day to complete the collection.

Designers created a day-to-evening ensemble for Banana Republic. A team event with five teams of two. Both designers on the losing team were eliminated. Each team had to finish their garment in one day. After that, all teams went to Banana Republic and each had to make a window that showed the idea of the dress; they had 30 minutes to buy all the materials they needed for the display and an hour to finish. The winner was chosen by votes from Banana Republic clients.

Designers took photos around New York and picked one to be an inspiration for an outfit. The designers had a budget of $100 and one day to complete the outfit.

This episode is most notable for Zulema's "Model Walk Off." Prior to this episode, all the winning designers stuck with their original models when given the chance to change by Heidi. Zulema stunned everyone when she not only announced she was changing models, but also making this decision by picking three girls to have a "walk off." She chose the eliminated Emmett's model Shannon, Andrae's model Danyelle, and Nick's model Tarah for consideration. She switched to Tarah, which left Rachael with Nick and eliminated Shannon.

Designers created a new look to make over a fellow contestant, who then modeled the new look on the runway. Chloe designed for Nick, Nick designed for Daniel V., Daniel V. designed for Chloe, Kara designed for Santino, and Santino designed for Kara.

The three final designers were shown at home when Tim Gunn visited them, and then returned to New York to prepare their collections for showing at New York Olympus Fashion Week. Back in New York, they were surprised to find out that they had to complete one final challenge: an additional garment that they each had to design with the aid of one eliminated designer of their choice. Nick, Andrae, and Diana returned to help Daniel V., Santino, and Chloe, respectively.
